  • contact with boiler water and at the steam and water interface. In watertube boilers, hard scale forms at the steam and water interface of the steam drum shell or flash chambers and on the inside of the boiler tubes in contact with boiler water. Hard scale has the appearance of a white or brown concrete and has a smooth texture. NB-410 Revision 3 5

  • The hardness of water is caused by calcium and magnesium ions which will vary greatly throughout the country depending on the source of the water. In boilers the hardness of the water can cause the formation of scale and sludge or mud. The hardness must be removed in the makeup water to the return system. Total hardness should not exceed 50 PPM

  • Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water quality is a critical aspect of implementing and operating an efficient steam plant.
